Heya Sonkun, glad to see you back!

Thanks man I’m glad to be back, I should be around more regularly now for the most part.

It’s a bit tricky with “bloom sampling” and your presets, because they more or less depend on magic glow for mask mitigation, so the differences are rather small.

Bloom pixel sampling is otherwise quite nice to dissolve small checkerboards etc. with non-ntsc/pal versions and to introduce a smart-smoothing look, deal with gradients etc. The effect strength is controlled by bloom pass sampling, so it’s quite versatile.

Needless to say, that it looks better with 16 bit games, compared with 8 bit ones due to color options, distribution and usage.

I see. That “smart-smoothing look” is what I like the most from it, gives the image that hazy crt like vibe. I went back and tried it again adjusting the “fine bloom/halation sampling”, it seems to give a better balanced look on 3.

First here’s no bloom pixel sampling:

Bloom pixel sampling on:

Bloom pixel sampling with bloom sampling set to 3 and both vertical and horizontal bloom sigma settings lowered to .25:

It makes a small difference. I’m not sure if I’ll incorporate this feature or not but I’ll see as I continue tweaking in the lab.
